To @ZZ whom it may concern.'

Be it known that l, lVALrnn E. B. JORDAN, a citizen of the United States, residing ait TWilson, in the county ot Vsfilson, State ol North Carolina, have invented certain new and useful Improvements in -Huller Ribs, of which the following is a description, reference being had to the 4accompanying drawing, and to the figures of reference marked thereon.

This invention relates to cotton gins, and more particularly to an improved form of huller rib adapted to prevent the choking of the cotton in the huller or outer breast of a double rib huller gin.

At the present time, considerable difficulty is experienced in ginning cotton-especially clean cotton, due to its tendency to string 1t self out from seed to seed and to be 'fed by the picker roller into the saws in such a manner that the severed end ot the string turthest from the saws is thrown up against overlying knees or projections on the under side of the huller ribs. The cotton strings catch on these projections to such an extent as to cause a gradual accumulation of cotton at these projections and consequently prevents the cotton 'from being properly carried into the inner breast, resulting in the breakage of the roll and a considerable loss of time in ginning. n

The present invention has for its object the provision of a huller rib constructed so as to eliminate or to minimize this objectionable choking.

A further object of this invention is to provide a standard rib such as described which can be quickly and readily substituted for the present type of huller ribs used in cotton gins.

These and other objects will in part be obvious and will in part be hereinafter more ullv disclosed.

Referring more particularly to the accompanying drawings Figure 1 shows a sectional View of .a standard double rib huller gin illustrating the design and location of my improved rib;

Fig. 2 is a side elevation of a single rib, and

Fig. 3 is a front view of the same.

In the drawings, the frame 1 of the cotton gin is arranged with the usual huller chamber 2, roll chamber 3, gin saw 4, brushes 5, and the picker roll 6. Adjacent the saws 4C in the spaces which separate the same in Specification o1 Letters Patent.

the saw shaft are arranged the usual ribs 7 through which cotton from the roll boi; 8 is pulled to Ytree it from seed prior to its passage on the saws to the lint removing brushes 9. All the foregoing is well known in the art. i

The huller ribs k10 which form the subject matter of this invention are disposed as usual with their lower endsy 1l ysecured as by screws or the like` to the portion 12 of the ra'ine l.

Said huller rib 10 is provided with a central outwardly bowed portion 13 and an upper portion 14 which extends forwardly from said central portion. The under surface 15 of the upper portion is formed on a continuous curve which merges into the curved portion 16 at the upper end of the central portion referred to. This upper portion 14; has a narrow neck 20 adjacent its end, and said neck portion terminates in a relatively wide securing flange 1S. Said flange is bent upwardly at 17 and is provided with an opening 21 through which suitable securing means is passed 'for se-v curing the upper end of the huller rib to its supporting rail. The forward under sur" face 22 of the securing flange is .curved upwardly to a point somewhat above the upper surface of the neck portion, and the ends 23 of the flange are also curved upwardly toward the upper face of the neck portion, and these ends are further curved so as to merge into the sides of the neck portion.

Clean cotton has a tendency to string out from seed to seed, and the outer ends of these strings when fed by the picker rolls 6 to the saws 7 are thrown upwardly by the action of the saws, and unless the huller rib is entirely free 'from shoulders, the cotton strings will catch on the shoulders and will accumulate. This is particularly true where there are any shoulders of any character at the upper end of the huller rib. The cling ing cotton will bridge over to the outside wall of the roll boX and prevent further4 feeding of the cotton to the inner rolls and cause its breaking.

In my improved form of huller rib where the securing flange is curved upwardly at its forward end and the rear ends are curved upwardly and curved so as to merge into the neck portion, all shoulders have been eliminated and this clogging and choking is avoided as the ends of the 'cotton strings f extending forwardly from said. central portion and having itsunder surface continuously curved and merging into the curved surface of the central portion, ,said upper portion having a narrow neck adjacent its end and vterminating` .in ra relatively wide securing flange, the ends of said flange adjacent the neck being curved and merging` into the'sides ofthe neck.

2. As an article of manufacture, a huller rib-for a cotton gin comprising,- a central outwardly bowed portion, and an upper portion extending forward from said central vportion and having its under surface continuonelyr curved and merging into the curved surface of the central portion, said upper portion having a narrow neck adjacent its end and terminating inl a relatively wide securing' flange, the forward under surface of Said flange being curved upwardly to a point above the upper face of the neck portion and the endsl of said flange adjacent the neck .portion being curved and merging into the sides of the neck portion. v

In testimony whereof, I affix ture.
